Engine life ?
 

anyone know the approx miles a standard (regular seviced) 748 lump should do before major rebuild....?
cheers :)

I've got a customer with a 748SPS that has at least 50000 kilometers on the clock now and it's still going strong.

ooer unc this sounds serious or do you have a bit of spare time to kill:o

My 748's done 41000 miles now, in 3 years.

What do you mean by "major"? To be honest, I don't see why it shouldn't run as long as any other motorcycle engine, as long as regularly serviced etc.

Apart from consumables like rectifiers and clutches :lol: (actually not *that* bad on that score), nothing's really gone wrong. The rockers were pulled at the last major service. One was replaced; all the others were fine. I was told that the cams still had the parkerising coating fully intact on them. On that basis, I don't imagine there's any serious engine wear to the bores, etc. Certainly it uses only a negligible amount of oil.

Of course, it's yellow, so that probably explains my relative lack of problems. :burn:

Just keep the throttle pined to the stop and tell us when it goes BANG :sing:

My old 1998 916 has done around 30,000 miles, the use has been track days blasts to assen commuting. At the last service I had the cams pulled and the rockers and cams were perfect only a couple of shims needed replacement and the compresion was the same as at the 500 mile service.
I have a major service (inc belts every year and only use top quality oil. the only wear you notice when riding it is a slight clonk over bumps which is the fork bushes.

If the botom end goes next week I would still think the engine had lasted well.
